6.4 LEAD LAG SETUP FOR UP TO 12
APPLIANCES
Honeywell SOLA can only support up to 8 boiler in a single
lead lag network, to sequence a second network of up to 12
boilers in total this will be activated through Pump C contact
of boiler #8.
Pump C is activated on a time delay algorithm where the
timer is initiated when boiler #8 begins the ignition
sequence. The delay timer is set based on the number of
boilers in network #1.
Pump C Delay Timer (Register #293) = Interstage Delay
(Default: 2 mins) x Number of Boilers. This delay timer will
allow all boilers in network 1 to perform an ignition attempt
before network 2 is initiated.
Due to the rotation of leaders in network 1; boiler #8 may
become lead boiler. Operation is not impacted regardless of
lead boiler in network 1 as all boilers in network 1 will
attempt to start before network #2 is initiated.
Network 2 operates independently of network 1 and as a
result the setpoint for network 2 is recommended to be set
at least 2
o
F lower than network 1. A staggered setpoint
approach will reduce the amount of short cycling when all
the boilers are viewed as a complete system.
Network 2 can support up to a maximum of 4 boilers.
9 Boiler Outdoor Reset Wiring
The use of outdoor reset requires two outdoor sensors for
this setup. Network 1 outdoor sensor is wired to boiler #2
and the outdoor sensor for boiler #9 requires the use of the
outdoor sensor module (PN: W8735S1000) wired to the
ECOM connection on the Honeywell SOLA.
Additional details can be found on page 77.
10 to 12 Boiler Outdoor Reset Wiring
The use of outdoor reset requires two outdoor sensors for
this setup. Network 1 outdoor sensor is wired to boiler #2
and the outdoor sensor for network 2 is wired to boiler #10
on the System/OutD contacts in the junction box.
Additional details can be found on page 78
6.5 LOCAL/REMOTE SWITCH
The local remote switch mounted inside the control box is
designed to deliver an enable signal either relying on an
external contact closure (Remote) or enabling the boiler
locally (local). When Remote is selected via the SPDT
switch the Remote Operator contacts in the junction box
must close to deliver an enable signal. When Local is
selected via the SPDT switch a constant enable signal is
present. When troubleshooting the DynaFlame® it is
recommended to switch to Local mode.
